Leaked Apple plans show a rebuilt Siri for iOS 27 running on Gemini with options to switch to ChatGPT or Claude

Bloomberg leaked Apple's full iOS 27 Siri redesign. Two years of delays, biggest update in Siri's history, etc. So what's the actual architecture? It runs on Google Gemini. And the new interface has a dropdown menu where you pick ChatGPT or Claude instead. Apple rebuilt Siri from scratch and the conclusion was apparently "let users choose someone else's model." Apple is also shipping: AI-powered web search that competes with Perplexity, natural language Shortcuts creation, and AI photo editing
